How does PRK surgery work?

PRK Surgery: The Ultimate Guide to Laser Eye Surgery and Medical Assistance

What is PRK surgery?

In the previous section, we discussed the basics of PRK surgery. Now let’s delve deeper into how this procedure actually works.

The process begins with the application of a local anesthetic eye drop to numb the eye. Once the eye is sufficiently numbed, a specialized instrument called a trephine or excimer laser is used to remove the thin outer layer of the cornea, known as the epithelium. This allows direct access to reshape the underlying corneal tissue using ultraviolet light emitted by the excimer laser.

During this reshaping phase, a computer-guided beam precisely removes microscopic layers from specific areas of the cornea according to your individual prescription. The goal is to correct any refractive errors such as nearsightedness (myopia), farsightedness (hyperopia), or astigmatism. By altering the shape of the cornea, light entering your eye can be properly focused onto your retina, resulting in improved vision.

Once the necessary corrections have been made, a protective contact lens may be placed on your eye to aid in healing while also providing comfort. Over time, new cells will naturally regenerate and cover the treated area, allowing for complete recovery.

  • Improved visual acuity without dependence on glasses or contact lenses.
  • Enhanced quality of life through clear vision during daily activities.
  • Greater freedom and convenience in recreational pursuits.
  • Increased confidence and self-esteem due to improved appearance.
Pros Cons
High success rate Temporary discomfort
Minimally invasive Potential side effects
